A Dallas County grand jury on Thursday declined to indict a former Dallas police officer on a charge of sexual assault.

Edward Antunez, 32, was fired last month after being arrested in June on the sexual assault charge. Antunez denied the allegations that were made against him.

It is unclear whether Antunez will be reinstated to the force, but the department has reinstated officers in similar situations.

In Antunez’s case, a co-worker told Mesquite police that Antunez sexually assaulted her on March 13. She didn’t come forward until more than two months later.

The co-worker is not being identified because The News does not generally identify potential victims in sexual assault cases.

She told police that Antunez and another woman had been visiting on the night of the alleged incident.

The co-worker told police that after the other woman left, Antunez asked whether he could watch a movie while the co-worker got ready for bed. The only TV in her home was in her bedroom, so he watched TV while she went to sleep.

The woman told investigators that she awoke as Antunez was sexually assaulting her.

Texas Department of Public Safety Sgt. Lonny Haschel says the case was referred to the district attorney’s office on Friday.

Investigators, says Haschel, “looked at everything — witness statements, the vehicle, driver records — and it all came back to the driver. They couldn’t find anything wrong with the vehicle. And in that case, they made the decision to turn it over to the DA’s office and let the grand jury decide if charges need to be pursued.”

Debbie Denmon, director of communications for the Dallas County District Attorney’s Office, says via email that the prosecutors in the grand jury division will now look at the DPS’s evidence “and see if the charge is appropriate.” If they determine that it is, they will take the case to the grand jury, which will indict or no-bill “based on the charge and the evidence collected,” she says.

Given that the DA’s office just got the case, she says, “It could take several weeks before the grand jury receives the case.”

Says Haschel, everything gathered during the investigation has been turned over to the DA’s office: “the crash reconstruction, the reports on the inspection of the bus itself, the inspection of the company itself — it’s a big packet of information to get everything they need to determine whether they want to indict.”

Rieve has escaped similar charges in the past: As we reported earlier this year, the April crash on the way to the Choctaw Casino in Durant, Oklahoma, was the second fatality accident involving the 65-year-old driver. But in 1998 a grand jury declined to indict Rieve on a charge of criminally negligent homicide when he was driving a tour bus and ran over a good Samaritan at an accident scene.
